Title: Holding construction of crystal oscillator
Inventor: NAKADA HOZUMI
IPC: H03H9/19
Filed: 1983-02-08
Abstract: PURPOSE:To prevent the frequency of a crystal oscillator from being changed by secular change and an adhering force of an adhering part of a pad of electrodes of the crystal oscillator by forming a metallic layer for preventing errosion and diffusion of the pad made of a soft metal and adhering a connecting part onto the metallic layer by the soft metal. CONSTITUTION:A holder lead wire 4 and the metallic layer 20a on the pad 3a are adhered as follows. That is, a prescribed amount of the soft metal 6 such as solder is provided to a contact part 4a between the holder lead wire 4 and the metallic layer 20a on the pad 3a, a thermal energy is applied to the contact part 4a so as to melt the soft metal 6, then the soft metal 6 is filled in the gap at the surrounding of the contact part 4a by the surface tension, and the adhering between the holder lead wire 4 and the metallic layer 20a on the pad 3a is finished by cooling and solidifying the soft metal 6. The adhering face between the metallic layer 20a and the holder lead 4 to be adhered is taken as a connecting part. Even if the so-called phenomenon such as errosion and diffusion of metal occurs in said metallic layer, it does not reach the electrodes made of the soft metal being an adhering member by adhering the metallic layer on the pad of the electrodes of the crystal oscillator.

Title: Tone ringer driving circuit device for telephone set
Inventor: KATO NAOYUKI
IPC: H04M1/00
Filed: 1987-01-29
Abstract: PURPOSE:To improve the sharpness of sounds by forcedly making an output OFF when a power source voltage becomes a value less than a specified value in a power source voltage detection circuit. CONSTITUTION:The power source voltage detection circuit 15 is added and when the detection circuit 15 detects that the power source voltage becomes less than the specified value, the output is forcedly made OFF. Therefore, the output which is not hitherto made OFF if the power source voltage does not lower to 10V, for example, is forcedly made OFF at 30V, so that the time of leaving the trace of sounds is made to be reduced. And if the power source voltage detection circuit 15 is made to have a hysteresis, namely if the output on-state voltage is set in 27V and the output off-state voltage is set in 25V, for example, the output can be prevented from repeating on/off by the AC signal superposed on the power source voltage. Thus, the sharpness of sounds can be improved.

Title: Manufacture of liquid crystal display element
Inventor: TORIGOE TSUNEMITSU
IPC: G02F1/133
Filed: 1988-02-01
Abstract: PURPOSE:To eliminate a defect in orientation by offsetting a solution formed by dissolving Si(acac)4 and Zr(acac)4 and removing low-boiling-point components previously as a film covering a transparent electrode, baking it and forming an insulating film, and then forming an orienting film on its surface. CONSTITUTION:The solution which contains Si(acac)4 and Zr(acac)4 is heat- treated previously to remove low-boiling-point components and then offset as the film covering the transparent electrode 3 on a glass substrate 1, and this is baked to form the transparent insulating film 6. Then the orienting film 4 is formed on the surface of the insulating film 6. A rise in viscosity due to the vaporization of the solution to invariably uniform film thickness, the transparent insulating film 6 has nearly the same refractive index as ITO, and static electricity on the surface of the orienting film 4 is not discharged into the transparent electrode because of the intervention of the insulating film 6. Consequently, the defect in orientation due to electrostatic discharging is eliminated.

Title: Operation of blast furnace
Inventor: UNO SHIGENORI
IPC: C21B5/00
Filed: 1980-02-21
Abstract: PURPOSE:To adequately adjust blast heating corresponding to the change in input/ output of heat in the furnace, in a low burden-level operation, by deviding the amount of coke properly, corresponding to the lowered level; most parts being charged at low burden level time, the remaining part at leveling up time. CONSTITUTION:A low burden-level operation is performed while comparing and monitoring the operational data with the past data and enable to change the level in the range to the bosh. The exessive coke amount is set to the amount of coke required to compensate for the calory contained in the burden which is reduced by lowered level and increased space and for the increased calory dissipation by the furnace body, not considering the compensation for the calory due to disturbance such as slip, blowing-through, or deposit dropping. The required coke amount is about 30-60% of the amount that considers external disturbance. At low burden- level, about 70-90% of the total is charged, the remaining 30-10% is charged a leveling up time. At the low burden-level time, the range from the shaft to the bosh is devided into two sections, for example; about 60-80% of the low-level burden amount is charged into the first section and the remaining, about 40-20% is charged into the next section.

Title: Sheet detecting mechanism
Inventor: TORISAWA NOBUYUKI
IPC: B65H7/02
Filed: 1991-02-13
Abstract: PURPOSE:To precisely detect the presence of a sheet by compensating the deflection of a drum between a first drum which always makes contact with the drum and a second roller which separatably make contact with a sheet held between the drum and a conveyer belt so that the presence of the sheet can be detected by a displacement of the second roller. CONSTITUTION:A photosensor 68 fixed to a support member 66 for a first roller 58 which makes always contact with a drum 24 is energized or deenergized by a detection piece 80 attached to a second roller 72 adjacent to the first roller 58 so as to compensate a deflection of a drum 24. With this arrangement, the displacements of the second roller 72 which is displaced by making contact with a photosensitive material 32 as a sheet fed by the drum 24 and a conveyer system 28 making contact with the periphery of the drum 24 is detected by the photosensitive sensor 68, thereby it is possible to surely detect the presence of the photosensitive material 32.

Title: Semiconductor integrated circuit device
Inventor: KUNIEDA TAKESHI
IPC: H01L27/06
Filed: 1983-02-09
Abstract: PURPOSE:To switch a power supply having a voltage higher than a dielectric strength between collector and emitter of an integrated bipolar transistor(TR) by adopting NPN or PNP TRs for the 1st-3rd TRs. CONSTITUTION:When a level at a signal input terminal 1 is high, a drive TRQ1 is conductive and the collector, i.e., a base of an output TRQ4 goes to a low level. As a result, the output TRQ4 is interrupted and then an output TRQ3 is also cut off. Since resistors R3, R4 are selected to equal resistance value, a voltage between the collector and emitter of the output TRs Q3, Q4 is nearly Vcc/2, then a high power supply voltage Vcc is shared equally by both output TRs Q3, Q4. Then, when the input terminal 1 goes to a low level, the drive TRQ1 is cut off and a current (i) flowing to a resistor R1 is shared into each base of the output TRs Q3, Q4.

Title: Engine starter
Inventor: AIGAMI KUNIO
IPC: F02N11/08
Filed: 1987-01-30
Abstract: PURPOSE:To prevent the cranking during the engine revolution by allowing a starter driving device to start only in the case when the number of engine revolution is below a start judging number or revolution and the discharge pressure of an oil pump is below a prescribed value. CONSTITUTION:The timer circuit 18 of a controller 30 for controlling the electric conduction of the starter switch 3 of a starter motor 10 is turned-ON by the H-level signal of an AND-circuit 23. The AND-circuit 23 receives the signal supplied from the contact point 12 of the hydraulic switch 11 of an oil pump through an inverter circuit 21 and an OR-circuit 22. Therefore, even if the number of engine revolution is less than a start judging number of revolution, the output of the AND-circuit 23 does not become the H-level state during the time when an engine 4 revolves at a low revolution speed, since the discharge pressure of an oil pump is high, and the cranking in the second time is prevented without operating the timer circuit 18 again. Therefore, a ring gear 6 and a sell motor 8 can be prevented from being damaged.

Title: Capillary writing utensil
Inventor: KOJIMA MIKIO
IPC: B43K5/00
Filed: 1992-01-09
Abstract: PURPOSE:To make the permeability of ink through an elastic product smooth and allow ink to be dispensed effectively even during high-speed writing process by arranging the elastic product of a polyurethane rib structure which is 50% or higher free from a foam filmy inside a capillary writing utensil. CONSTITUTION:The subject writing utensil consists of a bar 8A running through the folded part 8B of a center core 8 and an elastic product of polyurethane foam rib structure which is 50% or higher free from a foam film sandwiched between the folded part 8B of the center core 8 and the front end of a joint 7. The capillary writing tool equipped with this elastic product allows the ink, stored in the elastic product of a rib structure, which is led by the joint 7, to be pressed by writing action. This action results in the regression of the center core 8 and the subsequent compression of the elastic product 9. Thus the ink flows out of the elastic product 9 smoothly to be guided to the tip of a small diameter type 4. Consequently, if data is printed at high speed using a plotter, the ink would never run short to ensure smooth writing process.

Filed: 1993-01-14
Abstract: PURPOSE:To elevate the breakdown voltage of a folded gauge by forming a lightly doped conductivity type semiconductor substance region surrounding at least one of coupling part and lead-out part in a semiconductor substrate. CONSTITUTION:A differential pressure detecting gauge 2 forms a folded gauge where the gauge parts 2a, 2b have a predetermined sheet resistance of low concentration and the crystal orientation (100) is in parallel with the crystal axis (110) having maximum piezoelectric resistance factor. A coupling part 3 forms a heavily doped conductivity type semiconductor substance region coupling the gauge parts 2a, 2b. A lightly doped conductivity type semiconductor substance region 14 is formed in a substrate 1 surrounding the coupling part 3 and lead-out parts 4a, 4b while being isolated from the substrate 1. Since the depletion layer becomes thick and weakens the field, withstand voltage is increased and the breakdown voltage of the gauge 2 is elevated when a voltage is applied reversely to an (rn) joint.

Title: Heater utilizing coolant of engine
Inventor: TATENO HIDENORI
IPC: B60H1/00
Filed: 1978-02-27
Abstract: PURPOSE:To accelerate the heating effect by a heater by providing a variable blower discharge responsive to the temperature of coolant of an engine. CONSTITUTION:The coil 11b of an electromagnetic control relay 11 is connected at one end thereof to an ignition switch 12 and at the other to ground through a water temperature switch 15 closing at higher than special engine coolant temperature. Thus, when an ignition switch 12 is closed to start an engine, the coolant is circulated through a radiator 3 at flow rate set by a water flow control valve 6. While the coolant temperature is low, the switch 15 is opened to deenergize the coil 11b to thereby open the contact 11a to thus supply low voltage through a resistor 14 to a motor 10 to reduce the blower discharge so as to reduce the heat derived from the radiater 10 to thereby abruptly increase the coolant temperature. When the coolant temperature becomes higher than special temperature, the switch 15 is closed to close the contact 11a so as to short the resistor 14 to thus supply high voltage to the motor 10 to cause the motor 10 to rotate at high speed to increase the blower discharge so as to sufficiencly supply heat from the radiator 3 into an automotive room.
